9 0 whereupon the linger 31 so as to swing in relation to said lever.

The keeper 30 extends over the top of the push rod/Q2 to prevent tie linger 521, from becoming d splaced from the hole and the endot the keeper is bent into the fl'il'lll of a hook 352 which is movable in a slot ill at theend of the arm 8 of the lever B, the hook being held at the inner end or the slot 3% by means of: a coiled contractile spring 35 one extremity of "which is attached to the hook 32 While the other end is secured at the point, 36 to the frame of the machine. The tension of the spring serves to n'iaintaizi the keeper in the position illustrated in the drawings, the keeper maintaining the pivotal connection between the push l'tlil 22 and the bell crank lever B. In order to dis connect the rod from the lever D the keeper 30 is pushed forward beyond the hole may be lii ted out of place thus throwing the inzcclcrator out of use and enabling the boards,- of the floor 28 to be taken out.

From the foregoing description it will be seen that the throttle valve may be operated. either by hand or foot the loot accelerator being capable of n.--;c either independently of or siinnltanconsly with the hand throttle lever. This enables the operator to accele rate the machine by his foot alone, leaving both hands tree to manipulate the other coir trols o: the machine. The spring 255 serves to maintain the parts of the mechanism rcerred lo initheir proper relation to each other, while the spring cross-r d l absorbs the jar and \llllfiililll and thereby prevents undue- \v air on the bullcnlly val vc. and the limiting set s rew with which all carburetors are prmillcd tor the pin-pose of preventing the complete closing; of the throttle valve. The spring 35 and the croeshead 1 together with the .wpring arm 3 thereof serve in cinriinirlion with each other to maintain all parts oi the mechanism re ferrcd to under a tencion which will avoid any tendency to rattle and Wear.

What I claim i,

l. A toot accelerator for automobiles roinprising in combination with an internal ccn' bnstion. engine and carburetor, a bell crank lcvcr, a supporting bracket for eaid lever located on the opposite side of the engine from the carburetor, clamping means on said bracket. for fastening the/ latter to the water connection of said engine, a cross rod connecting eaid lover with the throttle valve of the carbnreter, a pedal shaft, an arm on said shaft, a push rod connecting said arm and bell crank lever, and a spring acting on said lever to hold the throttle normally closed.

2. A foot accelerator for automobiles coinp 'sing in combination with an internal coinbnstion engine. and carbnreter, a bell crank lever, a supporting bracket for said lever located on the opposite side of the engine from the carburetor, clarnping'means on said bracket for fastening the latter to the Water Lil'FZlllCCllOll of said engine, cross rod connecting said lever with the throttle valve of the carburetor, a pedal shaft, an arm on said ehatt, a push rod connecting said arm and bell crank lever, a spring acting on said lever to hold the throttle norn'iallv closed, said bell crankvlever being formed With a slot, and a keeper for said push rod pivotally connected to and carried by said bell crank lever and having a hooked extremity movable in said slot and having said spring attached thereto.

3. A toot accelerator for automobiles co1npri.-.ing in combination \Yi an internal co'nr bastion engine and carburetor, a bell crank lover, a supporting bracket for said lever located on the opposite side of the engine from the carburetor, clamping means on said bracket for fastening the latter to the water connection of said engine, a cross rod connceting said lever with the throttle valve of the carburetor, said rod having an end por-. tion thereof bent to form a spring arm \vhich is terminally connected to said bell crank lever, a pedal shaft, an arm on said shalt, a push rod connecting said arm and bell crank lever, and a spring acting on said lever to hold the throttle closed.
